FASTENER.

Specification of Letters Patent.

Patented Apr. 13, 1920.

Application filed January 31, 1919. Serial No. 274,310.

To all whom it may concern Be it known that I, FRED S. CARR, a citizen of the United States, and a resident of Newton, in the county of Middlesex, Commonwealth of Massachusetts, (whose postoffice address is care of Carr Fastener Company, Cambridge, Massachusetts,) have invented an Improvement in Fasteners, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention pertains to improvements in separable fasteners and more particularly, though not exclusively, to improvements in small fasteners such as placket fasteners and the like.

In the drawings, which show on an enlarged scale a preferred form of my invention 1- Figure 1 is an elevation of a preferred form of fastener connecting overlapping layers of fabric;

Fig. 2 is a vertical section on the line 22 of Fig. l;

Fig. 3 is a horizontal section on the line 3-3 of Fig. 1;

Fig. t shows a plurality of fasteners of the type shown in Fig. 1 in their cooperative relationship on the placket of a dress;

Fig. 5 shows the preferred form of socket;

Fig. 6 is an end elevation of the socket shown in Fig. 5-;

Fig. 7 is a section on the line 7-7 of Fi 5 Fig-. 8 shows the preferred form of stud;

Fig. 9 is a view of the stud shown in Fig. 8 taken from the bottom thereof; and

Fig. 10 is a side elevation of the preferred form of stud shown in Fig. 8.

Referring to the drawings and to the preferred form of my invention selected for illustrative purposes, I have shown a cooperating stud and socket in which one of the members, preferably as shown the stud 8, is resiliently expansibl e, the resiliency being provided by an upstanding spring element 11 integral with the body of the fastener member with which it cooperates. Where, as shown in the drawings, the spring cooperates with the stud element, I prefer, as shown in Fig. 8, to provide a relatively flat body portion 12 having projecting upwardly therefrom a stud comprising portions 13, 14: connected by the upstanding flange spring 11, which is preferably ofsubstantial length as shown and which is preferably extended at l5, 16 to stiffen the connection between the spring 11 and the body portion of the stud member, and also to stiffen the two separated halves of the body portion thereby to prevent the flexing of one relative to the other. The projections 18, 14C, constituting the stud proper are preferably wedge-shaped, as viewed in F ig'. 8, providing overhanging lips as best shown in Fig. 9, the latter preferably having on their 'under sides relatively abrupt shoulders '17, 18 adjacent the outer edges thereof.

The preferred form of stud, in the embodiment of my invention shown in the drawings, cooperates with a socket 19 having an opening 20 therein adapted to fit over the stud portions 13, let when the latter are moved'one toward the'other by flexing the spring 11 and to engage under the shoulders 1T, 18. By reason of the wedge shape of the-stud portions 13, 1a the socket may be separated therefrom by relative tipping movement of the stud and socket in one direction only, the sides of the aperture 20 serving to press together the stud portions 13, i l and thereby to release the socket from engagement with the abrupt shoulders 1T, 18 when the stud and socket are tipped in such a direction as to bring the sides of the aperture '20 into engagement with the smaller end of the wedge provided by the stud portions 13, 14.

The studand socket preferably, as shown, project beyond one another at the opposite ends of the fastener, so that, if desired, separation may be effected by squeezing both ends of the fastener, one toward the other, which results in a springing out of the lower portion of the socket over the narrow portion of the wedge of the stud pertions 13, let.

The preferred form of fastener is primarily adapted for use on a flexible fabric, and this flexibility of the fabric enables the opposite portions of the expansible fastener element to spring together and apart when the fastener member having the resilient portion 11 is stitched or otherwise attached to the fabric.

lVhile I have shown the flexible element as carrying the stud, it is obvious that the Lin] spring 11 may in some instances be formed on the socket member, the latter being made eXpansible and the stud rigid. Similarly, it is obvious that while I preferably provide the smaller ends of the wedge-shaped stud elements 13, 1A adjacent the resilient element 11, I may, if desired, reverse the relative position of the broad and narrow ends of the wedge-shaped stud.

While I have shown and described one embodiment of my inventiomit will be.understood that changes involving omission, alteration, substitution and reversal of parts, and even changes in the mode of operation, may be made without departing from the scope of myinvention, which is best defined in the following claims.

Claims:

1. A separable fastener comprising, in combination, a stud and socltet, one of which has a body portion in plan split substan 'tially its whole length and provided with an upturned spring portion at one end there of, said spring portion being of a width substantially greater than its'thickness and integral with said body portion.

A separable fastener comprising, in combination, a studand socket, one of which is in plan split substantially its whole length and provided with an upturned spring portion at one end thereof, said upturned portion being continued at each end to provide stiffening ribs opposing relative twisting movement of the substantially divided portions of the split member.

3. A separable fastener comprising, in

combination, a stud and a socket, one memb er of which is split substantially its entire length and provided with a connecting spring portion at one end, the opposite sides of said member being relatively movable toward and away from each other and each having provision for direct connection to a flexible carrying fabric adapted to yield when the opposite sides of said member are moved one toward the other.

l. A separable fastener comprising, in combination, a stud and a socket, one member of which has a body part split substantially its entire length and provided with a connecting spring portion at one end,said

spring portion integral with said body, the

opposite sides of said member being relatively movable toward and awayfrom each other and each having provision fordirect connection to a flexible carrying fabric adapted to-yield when the opposite sides 7 6. A separable fastener comprising, in

combination, stud and socket members, one ofsaidmembers having a body part split substantially its entire length and having an integral upstanding metal spring portion at one endthereof resiliently connecting the two otherwise substantially. divided portions thereof, said members separable by relative tipping movement in one direction only.

.7. A separable fastener comprising, in combination, a stud and socket, one of which isv in plan split substantially its whole length and provided with a spring portion atone end thereof, said spring portion having a width substantially greater than its thickness, the greater dimension thereof being substantially at right angles to the plane of relative movement ofthe opposite sides of the split member. r V

8. A separable fastener comprising, in combination, a stud and socket, one of which is in plan split substantially its whole length and provided with an upturned spring portion at one end thereof, said stud and socket beingseparable by'relative tipping movement in one direction only.

9. A separable fastener comprising, in combination, a stud and socket, one of which is in plan split substantially its whole length and-provided with an upturned spring por-' tion at one end thereof, said spring portion being provided with ribbed eXtensions'p-aralleling the outside edge of the spring-carrying part.

10. A stud for fasteners comprising a'flat plate split substantially its entire length and having an upstanding metal spring portion at one end thereof connecting the twootherwise substantially divided portions thereof, said divided portions each carrying one-half of an upstanding projection constituting the stud. r

In testimony whereof, I'have signed my name to this specification. I
